"Hey, this little mouse actually got under the roots of those trees? Is this a cave?" Gu Zhengyan was surprised for a while, but he didn't expect that under those hard tree roots, there was a cave of dozens of square meters in size.

This made him very curious, so he took a closer look, but when he looked at it like this, he was dumbfounded.

it!

A lot of fairy crystals......

At this moment, in his shared field of vision, the little mouse was holding a piece of fairy crystal the size of a millstone and gnawing on it, which was very funny, and it also looked up from time to time to look up at the exposed fairy crystal on the cave, and took a bite at a glance, and then a bite at a glance.

Looking at it like this, those days were simply unhappy, and there was no such miserable appearance as just crying.

Gu Zhengyan roughly counted it through its vision, but the number of immortal crystals exposed in that cave was already several times the harvest that he had worked hard for half an hour to dig up.

"Beast, this immortal crystal vein was discovered by your master and me first, how can you enjoy it exclusively?"

When he got such a data, his saliva was about to flow out, and he hurriedly ran to the giant pit where the Soul Devouring Golden Rat was, and jumped down.

When he went down, his eyes scanned, and soon he found a hole the size of a fist in the net of the tree roots, and even those hard roots were bitten through.

Without hesitation, he gave an order for the Soul Eater Golden Rat to hurry up and make a way for him to enter the cave.

After receiving his order, the little mouse didn't dare to slack off, and hurriedly put down the fairy crystal the size of the grinding plate, and with a leap of his small body, he jumped into the small hole on the top of his head and began to bite in it.

Seeing that the little mouse easily bit off those tree roots, Gu Zhengyan was a little shocked in his heart, this pair of teeth of the little mouse, cow beep.

It's only at the V1 level, and the edge of its teeth is already far beyond the Ziyang Mountain Knife, so if it grows up, how powerful will this pair of teeth be?

"Roar~!"

At this time, there was already a howl of demon beasts outside the valley, but the sound that came from it made Gu Zhengyan feel very familiar, and soon, an answer appeared in his mind.

Black Tiger?!

Could it be that the Black Tiger's kindred is here?

"Ding, host, dozens of demon beasts have appeared around the valley, you can't leave now if you want to, if you want to enter that cave, you need to do it in two seconds, and if you want to leave the Journey to the West plane, this system can send you away now. ”

Gu Zhengyan's eyes flashed slightly, and being surrounded by dozens of demon beasts still made him a little nervous, these demon beasts were not comparable to those rats.

But at this time, his eyes lit up and said, "Don't go back first, this passage, okay!"

Before the voice in his heart fell, he saw the head of the Soul Devouring Golden Rat come out, and then circled around, quickly gnawing the roots on the surface.

And those tree roots and scum were swallowed by it, and it seemed that it was just a fist-sized body, but it actually swallowed at least dozens of times the roots of the tree, which seemed a little incredible.

For this reason, Gu Zhengyan now knew, because with that mysterious feeling, he could perceive that in the little mouse's body, there was an innate internal space, which was like its stomach, used to store and refine the items it devoured.

It is precisely the existence of this internal space that makes it possible for it to grow rapidly, otherwise with its small body, I am afraid that it will have to support it even if it eats a bite of the roots.

"Master, Maomao has dug the passage. ”

After biting this passage, the little mouse suddenly jumped on Gu Zhengyan's shoulder, rubbed his furry head, and asked Gu Zhengyan for credit.

Gu Zhengyan was naturally very satisfied with the little mouse's efficient burrowing ability, and as soon as his body jumped, he immediately jumped into the just right root cave, and at the same time sent a wave of admiration to the little mouse in his heart.

But in the end, he asked with some curiosity, "How do you call yourself Mao Mao?"

Judging from the data, it was only half a month after the little mouse was born, and such a little rat actually called himself Maomao? This really made him a little confused...... Ahem, surprise.

"That's the name my mother gave me, but she has been killed by those bad rats, woo woo, little Mao Mao is so pitiful, as soon as she was born, her mother died, if it wasn't for Mao Mao's teeth, she would have been killed by those bad rats. Woo woo, mother is so pitiful, Mao Mao is so pitiful, woo woo, master, you can't eat Mao Mao's thighs, right?"

The little mouse said, a pair of little eyes were full of tears, and instantly turned into poor little Maomao, and they all looked pitiful.

In a few seconds, Gu Zhengyan landed on both feet, the depth of this cave is at least 100 meters, of course, this is plus the giant pit of more than ten meters he dug, so that the roots of the tree are dozens of meters thick, if it weren't for the Soul Devouring Golden Rat, he really couldn't get in.

Before he could comfort the little mouse, the moment he landed, there were several shocking beast roars from the hole, followed by a shock, which frightened him so much that he quickly reined in his breath and did not dare to exud the slightest.

The area where this valley is located is rampant with V5-level demon beasts, and it's hard to say that they can't cut off these tree roots, and at that time, he can only run back to Blue Star.

He was vigilant for a while, and found that the demon beast above could not destroy the root defense layer, so he relieved himself, and comforted the little mouse a little, and his eyes were on the cave in front of him, but to be precise, it should be on the exposed fairy crystals on the cave wall.

The purpose of his entry was these immortal crystals.

"Although these immortal crystals are not many, they can at least compensate for my loss. ”

Gu Zhengyan's eyes were shining, this can be regarded as an unexpected gain, before leaving, he gave him such a little comfort in his soul, and the surprise reappeared, which made his impression of this trip not so bad.

However, at this time, the little mouse that was still on his shoulder, the immature voice sounded in his head, and then the prompt of the system also sounded.

"Master, do you like these hedrons too? There are so many here, Mao Mao likes it very much. And Mao Mao can feel that as long as I eat all the spars here, I can evolve to the growth stage. ”

"Ding, host, Soul Devouring Golden Rat needs countless energy support for every evolution, their growth period, combat power is between the v4~v6 level, according to its current state, it is estimated that it can be reached within three years. ”
